Subject: madvise: Use split_vma() instead of __split_vma()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1176802f40335b5c7fbd78e7a88f8f3e899a55b5;p=users%2Fjedix%2Flinux-maple.git

madvise: Use split_vma() instead of __split_vma()

The split_vma() wrapper is specifically for this use case, so use it.
